Reactions of Molybdenum with Other Elements
Two Compounds containing it:
1. Molybdenum trioxide - adhesive betwee
enamels and metals
2. Molybdenum disilicide - electrically
conducting ceramic
Importance of Molybdenum
Lewis Dot Structure:
Molybdenum is alloyed with steel making it stronger and heat resistant.
Alloys are used for things as rifle barrels and filaments for lightbulbs.
It is also important for lubricant and chemical industries. Can also be
used for catalysts, paint pigments, corrosive inhibitors, and flame and
smoke retardants
